Is this vulnerability remotely exploitable?

Yes, if an attacker can influence the corpus parameter through any remotely accessible pathway (such as a web API, task submission interface, or externally writable configuration), they can typically exploit this issue without local access.

What access level does an attacker need to exploit this?

The attacker must be able to supply or modify data that is ultimately passed into the corpus argument of _extractLLM(). If that data originates from user requests or untrusted sources, the required access may be as low as basic network connectivity to the exposed interface.

What is the safest general fix pattern?

The most robust fix is to stop building shell commands with untrusted data and instead use parameterized process execution APIs that pass arguments as arrays. Combine this with strict validation of allowed corpus formats and avoid any dependence on shell-specific parsing of user-controlled content.
